This is a very large US trilobite. It is an impressive Trimerus delphinocephalus from Middleport, New York. This is one of the rarer types of trilobites from the Rochester Shale. This specimen is complete and is well over six inches long - very few types of trilobites found in the United States are this large. The sleek specimen has nice coloration and very good detail. The thick shell exoskeleton is very well-preserved. The bug is beautifully centered on the large, squared block, not on the edge of the plate like most. The fossil is laying on its left side, not missing those parts. The trilobite is also very inflated and 3-D for this type. This is a huge, displayable example of this uncommon species of trilobite.
